SPECIFICATION forming part of Letters Patent No. 245,462, dated August 9, 1881.

Application filed February 16, 1881. (Model.)

To all whom it may concern Be it known that I, HENRY B. DUMMER, of \Vest Troy, in the county ofAlbany and State of New York, have invented a new and Improved Lunch-Box, of which the following is a full, clear, and exact description.

The object of this invention is to provide a lunch-box in which tea, coffee, and other liquids can be carried and heated.

The invention consists ot'abox provided with double bottom and sides forming a space or chamber all around the box for holding liquids, which chamber 1s closed at the top, with the exception of an orifice through which it may be filled and emptied, said orifice being provided with a suitable stopper for preventing the escape of the liquid.

Figure 1 is a plan of the box with parts broken away to exhibit other parts. Fig. 2 is a longitudinal sectional elevation of the same on line at m, Fig. 1.

Similar letters of reference indicate corresponding parts. I

In the drawings, A represents the body of the box, of which a is the bottom, I) the sides, and c the ends, and d f 1 represent respectively the false bottom, ends, and sides that are set within said box-body A, and secured in place by a narrow plate, It, that connects the upper edges of the ends and sidesfg with the box-body A and forms the partition tor the chamber B, that is formed between the bottom, sides, and ends a b c, and the bottom, sides, and ends (I gf. This chamber B is designed for holding liquids, such as coffee or tea, 8210., which liquids may be warmed by placing said box on a fire or stove.

In the chamber-partition his an orifice, l, for filling or discharging Slld chamber B,'ancl a stopper, 0, designed for said orifice l,is secured by a chain or string, m, to some convenient part of the box A, on the inside thereof. An inner bottom, 1), removable at pleasure, is laid on the bottom d, for supporting the solid contents of the said box and preventing them from distorting by their weight the said bottom d.

E is the cover of the box A, closing down on the heading a. Said cover E may be fastened by lock or catch in the usual manner of lunch-boxes.

Having thus fully described my invention, I claim as new aml desire to secure by Letters Patent- 1. As an improved article of manufacture, a lunch-box constructed substantially as here.- in shown and described, with a chamber for liquids extending over its bottom and around its sides and ends, and provided with an inner bottom, substantially as set forth.
